- Page 2 Reading. Example: The line on beam and on the left of vernier edge is ‘1.2’…………..……=1.2” The point of needle is close to line ‘18’ of graduation on dial face…..=0.018” ------------------------------- The reading is…1.128” Page 1...
- Page 3 Always apply constant force on thumb wheel during measurement and zero setting. Tighten locking screw to hold reading. Measuring faces should be carefully protected from being scratched or damaged. Do not operate abruptly, drop or strike caliper. Page 2...
- Page 4 ELECTRONIC DIGITAL CALIPER Clean measuring faces before use. Remove cutting chips, dust, burrs and other foreign substances from the piece to be measured. Buttons: ‘inch/mm’ is for mm and inch conversion. ‘OFF’ button is to turn off display. ‘ON-ZERO’ is to turn on display or set the reading on display to be zero.
- Page 5 Measurement: One battery will last for one year of continuous use. If there is nothing on the display or the digits flash, battery voltage is too low, please replace battery (the positive side of the battery should face out). If digits do not change when buttons are pressed or vernier is moved, take out battery and put it back after 1 minute.
- Page 6 VERNIER CALIPER PRECAUTION: Clean the caliper before use. Make sure the measuring faces are clean. Remove cutting chips, dust, burrs and other foreign substances from the piece to be measured. Make sure that the zero lines of the vernier scale coincide with the zero lines of the main scale when the external jaws are closed.
- Page 7 How to read Example 1 A: 32 B: 0.54 ---------- C: 32.54mm Example 2 A: 2.05 (2” + 2 X 1/40”) B: 0.012 ------------ C: 2.062” A is the line of the main scale which is on the left of the zero line of the vernier scale. B is the line of the vernier scale which coincides with a line of the main scale.
- Page 8 measuring faces be in good contact with the workpiece, meanwhile the clamping screw must be loose. Precaution for measurement: It is important to apply suitable measuring force on the caliper to get accurate reading. Always use knob of 2310 or the fine adjustment of 2311.
- Page 9 ELECTRONIC DISC BRAKE CALIPER repair part number: DRG6059-2 RS232 computer interface cable (optional) DRG6059-3 fitted case Clean measuring tip and face before use. Remove cutting chips, dust, burrs and other foreign substances from the rotor to be measured. Buttons: ‘mm/inch’ is for metric and inch reading conversion. ‘ABS’...
- Page 10 again if necessary, the relative zero point is not changed until ‘ON-ZERO’ is pressed to set a new relative zero point. ‘ON ZERO’ is to turn on/off display and set the reading on display to be zero. Press it to set zero reading. Keep pressing it for three seconds to turn off display.

- Page 12 Specification: Resolution: 0.001mm / 0.00005” Accuracy: 0.003mm / 0.00012” Repeatability: 0.001mm / 0.00005” Measuring force: 5 – 10n Power consumption: ≤ 10 µ A Max. measuring speed: 80mm/s Operation temperature: 0-40ºC Date Output: RS232C Power: One silver oxide cell SR44W or SR44 for continuous use of one year.
- Page 13 OUTSIDE MICROMETER Clean the micrometer gently before use. Make sure the measuring faces are clean. Remove cutting chips, dust, burrs and other foreign substances from the piece to be measured. Standard rod and adjusting wrench: They are used to calibrate micrometers. Micrometers should be calibrated frequently.
- Page 14 be the same as the length of standard rod when the micrometer ‘measures’ the rod. For example, when 5607 (25-50mm) ‘measures’ its standard rod 25mm, the reading must be 25mm exactly. Otherwise you should adjust the micrometer. Put the small point of the adjusting wrench into the small hole on the sleeve which is near the locking lever, rotate the sleeve to make the zero line of the thimble align with the horizontal line of the sleeve.
- Page 15 Never rotate the thimble to let the spindle contact with the workpeice, which may damage the precision thread inside the sleeve. Please grip the heat isolation plate if you hold the micrometer for a long time, in order to prevent heat transferring from your hand to the micrometer.

Page 16: Dial Indicator
Reading 5603: Dial face has dual directional graduation of 0.001”. Revolution counter is graduated in 0.1”. One full revolution of large pointer is one increment of revolution counter. - Page 17 The large pointer is close to line ‘21’ of black digit=0.021” So the reading is 0.1”+0.021”=0.121” Or 0.6”+0.021”=0.621” Reading 5604: Dial face has dual directional graduation of 0.01mm. Revolution counter is graduated in 1mm. Once full revolution of large pointer is one increment of revolution counter. Example: The small pointer is between ‘1’...

Page 20: Magnetic Base
MAGNETIC BASE Fix all dial indicators with 8mm diameter shank and lug back with 6.3mm or 1/4" diameter mounting hole Page 19... - Page 21 Turn off magnet when magnetic bases are not in use. Use find adjustment to adjust the position of dial indicator slightly. Keep all setups as short as possible. Unnecessary length from dial indicator to the base increase the undesirable possibility of dial indicator movement.
